Tech 3 vs FAST

[TTA89]

Just curious on Pro's and Con's? Seems most people are running FAST systems, the Tech 3 looks pretty cool so why aren't more people using it?

I guess what I am looking for is what made you buy your current system over another?

Dont everyone speak up at once!

The FAST has wide band O2 control, the TEC 3 does not. The TEC 3 though is a nice system and I know of a lot of folks that have installed them with great success.

The TEC^3 will work in closed loop with an external WB02, it just doesn't have the controll circutry inside the box.

I ran FAST (batch fire) in my 800 rwhp Mustang Cobra in 2001. Made over 100 low 9 second passes. I took it off in 2002 in favor of Tech III because I didnt want to try to monkey around with a way around the Ford EDIS problem (spark blowout at 8000). Blew the motor up after one race.
I put FAST back on (upgraded to sequential) and I will never ever go back. FAST rules.
